Creamy Baked Chicken Cordon Bleu Casserole

Preheat your oven to 375°F (190°C). Lightly grease a baking dish with butter or cooking spray.

2. Layer the Casserole
Spread the chicken pieces evenly in the dish.

Sprinkle the diced ham over the chicken.

Lay Swiss cheese slices on top, covering everything.

3. Make the Creamy Sauce
In a bowl, whisk together heavy cream, Dijon mustard, garlic powder, onion powder, salt, and pepper.

Pour the sauce evenly over the layered ingredients.

4. Prepare the Topping
In a small bowl, mix panko breadcrumbs, melted butter, and Parmesan cheese.

Sprinkle the mixture over the casserole for a crispy, golden topping.

5. Bake & Serve
Bake uncovered for 25–30 minutes, or until the chicken is cooked through and the top is golden brown.

Let it rest for a few minutes before serving.
